Skipping the Spider Ball: Great Tree Hall

The Spider Ball track here is in the upper half where two
Bloodflowers reside. After locating them go in the alcove the higher Bloodflower
is in, then turn to face the track and make sure your view of the room is like
the above picture. Notice how the track is made up of horizontal pieces as well as vertical? The
horizontal parts can be landed on. L-lock your view and Space Jump to the
horizontal piece in the above picture. There isn't much room for error here
because it's easy to go too far and slide off the track, but it shouldn't be
hard to land on the piece either.

The track's next horizontal piece is right
above you now; look up so you can see exactly where, then lock the view again
and Space Jump on it.

Next, jump on the round top of this part of the track. This is very important to
do because you need to be at the highest point possible before the next step. Once on it, look up to see that you're right below the ground at
the top of the room where the ice door going to Life Grove Tunnel is. That's the
next place you need to get to somehow, but Samus will just hit her head if you
Space Jump straight up. L-lock the view so you can keep track of where the
ground is above you, then jump off the track and move away from it.
As soon as the ground above isn't blocking your way up anymore and you think
nothing would stop your movement, use your second jump and move back in the
direction of the track to land on the ground you were just looking up at
earlier.

Now you can go into the Life Grove and pick up the Artifact and X-Ray Visor.
After getting the Visor, you can do some interesting things, for instance, you
can use it to actually see (and lock on to) the Shadow Drone in Central Dynamo.
